The United States and Mexico are on the brink of a major agreement on the sharing of water from the Colorado River Basin.  UNM water expert John Fleck calls the agreement a win-win and another great step forward in the rational allocation of the American Southwest’s most necessary resource.  In the face of a 17 year drought, dented only a bit by a wetter 2017, more people in the southwest, city-dwellers and farmers, have learned to use less water.
